    Copper Range bought the Naumkeag in 1931 but conducted no work on the property. The Naumkeag is a perfect case of a mine where rich copper is known to exist at depth but too costly and dangerous to recover. Today very little of the original minesite exists. What piles remain can produce some very nice analcime groups.
